Research demonstrating links between sensation-seeking and drug use, and se
nsation-seeking and participation in leisure activities suggests designing
substance misuse prevention projects that encourage substituting alternativ
e activities for drug use. The current study uses factor analysis and discr
iminant analysis to provide comprehensive information on the kinds of activ
ities high-sensation seekers participate in. Factor analysis of activity pa
rticipation indicates an eight factor solution. Discriminant analysis of fa
ctor scores indicates that high-sensation seekers can be discriminated from
low-sensation seekers on the basis of two factors, active-adventure and co
nflict-combat. Implications for prevention program design are discussed.
